The top padding on the dock is auto generated based on the vertical grid, but I can still tweak the bottom padding some. Send over a screenshot so I can compare to P6 and find a happy median.Good job! Black folder background now works on Pixel4a.
For the records:
substratum lite overlay helper 0.5.20
pixel tweaks helper searchbar removal 126.96.36.199 (flashed over 188.8.131.52 with magisk)
pixel tweaks 6.3 (apk) installed after uninstalling 6.2 version
Works like a charm! Applause for @eg1122
If I really have to find a flaw, I'd say that the dockbar still needs a bit more padding, top and bottom.
But heck, no, I'm really happy with my current config.
